Thanks for the response Saurabh.
Yes, my extn has been filed in ‘reg’ before before L-1 I94 expired.
A few things that bather me -
1. waiting for H1B petetion result? Does USCIS has any deadline dates after which no petetion can wait for a result?
2. What (and how) if my H1 petition approves before Oct1 and L1 A Petetion extn is still in 'progress' as on this date?
3. In case of (2), how better can I react with my current employer/future employer? Should I inform USCIS/current-Employer to stop L1 process as on Oct1st?
Could you please advice? Thank you.
